Found another error in windows.getAll() when trying to write a test case. Will provide a fix for it here as well.

Thanks for fixing it. It looks nice aside from an issue in the test.

I don't think this does what you want. It waits until |window| (which is always |window1| here) is in focus. I think you want to check if Services.focus.activeWindow == <desired-window>. If it's not, you can add a "focus" listener on <desired-window> and wait for that.

::: browser/components/extensions/test/browser/browser_ext_windows_update.js:8
(Diff revision 1)
> +  let window1 = Services.wm.getMostRecentWindow("navigator:browser");

This is just the pre-defined global |window|, so you could just say |let window1 = window;|.

::: browser/components/extensions/test/browser/browser_ext_windows_update.js:12
(Diff revision 1)
> +  yield promiseWaitForFocus();

I think you might be getting lucky here. Most of the time, the focus will still be on |window1| at this point. You should probably pass |window2| in as an argument to promiseWaitForFocus so that it knows what window to wait to be in focus.
